Build an installed quote, compare lifetime costs and calculate material packs. Separate payment-day cash from later reimbursements using your project records.

Compare complete daily temperature profiles or test explicit heating and cooling cost changes, recurring fees, upfront cost and simple payback.

Calculate an entered utility bill reduction and simple payback, or compare observed bill averages without assuming what caused the change.

Calculate service dates from documented intervals or compare actual runtime readings with a service threshold, then save and export the record.

Compare actual filter MERV ratings and measured or published pressure drops at one airflow against an assessed filter allowance.

Normalize comparable duct pressure-test records or model sensible transfer and electric cost using separately supported operating leakage assumptions.

Calculate CFM from an explicit air-change target or sensible load, then compare design and measured room airflows without hiding individual deficits.

Compare a documented blower airflow and external-static point with the stated design airflow band and pressure limit, retaining signed margins.
